Planet in a Watercolor Tower Observatory

A watercolor painting of an ancient stone tower interior turned into a serene observatory. In the center, a translucent glass sphere floats, housing a detailed planet with swirling oceans and cloud bands, softly glowing from within. Surrounding shelves hold old maps, brass instruments, and a weathered telescope; spiral staircase coils around a central pillar. Tall arched windows with stained glass flood the room with warm amber, rose, and lilac light that bleeds across rough stone and wooden beams. Vines creep along the corners, dust motes drift in the glow. The painting uses wet-on-wet watercolor technique, loose edges, delicate color bleeds, grainy texture, and a dreamy, surreal atmosphere. Hyper-detailed yet painterly.
